Let's just say USAirways closes its doors. No chapter 11, just shuts down, like the Old Midway. Let's say I have a Swissair award ticket for travel after US ceases operations, obtained with redeemed US miles. It is on US ticket stock. Will this ticket still be valid? I assume it would as it would have been 'paid for' by US to SR upon ticketing, thus a done deal. Any insight? I know this barely happens and there isn't much precendent, however.
